Connection - CM Error Codewords

We've been having connection issues for a couple of weeks now and it's been getting progressively worse. We've had two tech's come out. The first tech installed a splitter. The second tech installed a "new' modem and still we lost connection several times a day. We now have a brand new modem and we've checked all connections including running a direct line from the modem to the cable box. Please see below for the CM Error Codewords and other information. At this point we need a tech to come out and check all connections as well. I've had to personally go to the local Xfinity store and speak with tech's there. Reaching a live agent is impossible and Xfinity Assistant will not allow setting an appointment if at that moment the internet is connected and there doesn't seem to be a problem. We had an appointment yesterday for a tech to come here but the appointment was cancelled by Xfinity. This problem is interfering with my job. I work from home and rely on the internet to perform my work responsibilities. I would greatly appreciate a resolution to this problem as soon as possible.
